Pre-purchase inspection: used car checklist before you buy
A pre-purchase inspection is a check of a used car by an independent mechanic before you pay. Consumer Reports says it usually costs about $100 to $150. Before that, do your own walk-around with this used car inspection checklist: the papers and recalls, the body, tires, under the hood, inside, underneath, and a test drive. Download the printable checklist (PDF) or the spreadsheet version (CSV).

- Printable PDF: one letter-size page with check boxes for every section below, plus lines for the VIN, mileage, asking price, and notes. Print one for each car you look at, so you can compare them later.
- Spreadsheet (CSV): the same items in rows, with columns for the result and notes. Open it in Excel, Numbers, or Google Sheets.
Bring a flashlight, a paper towel, a quarter for the tread, and a friend if you can. Consumer Reports suggests looking in daylight on a dry day, because rain and bright lights hide body flaws, and asking the seller not to drive the car for about an hour before you arrive, so you can check it cold.
Before you go: papers, title, and recalls
- VIN. Get the 17-character VIN from the seller. It should match on the dashboard, the driver’s door jamb, the title, and the registration.
- Open recalls. Enter the VIN at nhtsa.gov/recalls (free). Consumer Reports recommends not buying a car with an open recall until it’s fixed; recall repairs are free at a dealer for that brand.
- Title. The seller should have the actual title, in their name. Check it for words like salvage, flood, rebuilt, or lemon buyback, and for a lien. An NMVTIS title report shows title brands, total loss, and the last odometer reading.
- Service records. Ask for receipts and the maintenance log. How to fill the gaps: how to check a car’s service history.
- At a dealer: the Buyers Guide. The FTC requires dealers to post a Buyers Guide on every used car. It says whether the car comes with a warranty or is sold “As Is - No Dealer Warranty.” Keep a copy.
Outside the car
- Body panels and roof: dents, scratches, rust, and paint that doesn’t match from panel to panel
- Gaps between panels that are uneven, and paint on rubber seals: signs of repair after a crash
- Doors, hood, and trunk: open and close each one; seals not torn
- Glass: cracks (small chips are something to negotiate on)
- Lights: every bulb works and no lens is cracked or fogged
- Suspension: push down hard on each corner; the car should bounce back once and settle
Tires and wheels
- All four tires the same brand, model, and size
- Tread depth: at least 2/32 inch, the usual legal minimum; use a quarter to see if the tires will need replacing soon (how long tires last)
- Even wear across the tread; wear on one edge can mean an alignment problem
- Sidewalls: no cuts, cracks, or bulges
- Tire age from the DOT date code (tire age calculator)
- Spare tire or repair kit, jack, and lug wrench are there
Consumer Reports adds that a car with fewer than about 20,000 miles should usually still have its original tires.
Under the hood
Look with the engine cold.
- Engine oil: not gritty. Gray, foamy oil or water droplets on the dipstick are serious warning signs.
- Coolant, brake fluid, and power steering fluid between the marks on their reservoirs
- Transmission fluid, if there is a dipstick: the color and level the manual describes (often pinkish red)
- Belts and hoses: firm, not cracked, frayed, or soft
- Battery: no corrosion on the terminals; a date label older than about 4 to 5 years means a new one is coming (Consumer Reports)
- Leaks, fresh oil spray, or a very clean engine on an otherwise dirty car
Inside the car
- Smell: a musty smell can mean water leaks or flood damage; a sharp smell can mean smoking
- Warning lights: they should light up briefly when you turn the key, then go out once the engine runs (what dashboard lights mean)
- Seats, belts, windows, locks, mirrors, and the sunroof all work
- Heat and air conditioning blow hot and cold
- Radio, Bluetooth, and phone connection work
- Pedal rubber and the steering wheel: heavy wear doesn’t match low miles
- Headliner, carpets, and the spare tire well: stains, dampness, rust, or silt
Under the car
- Puddles or stains where the car was parked
- Black, greasy soot in the tailpipe (can mean burning oil)
- Torn rubber boots at the axle ends (CV joint boots), with grease thrown around
- Bent or kinked metal, new welds, or fresh undercoating that can hide crash repairs or rust
The test drive
Drive long enough for the engine to warm up fully, on local streets and on the highway, if the seller agrees.
- Starts easily from cold, with no warning lights left on
- Smooth shifts, no slipping, flaring, or hard clunks
- Brakes: straight stops, no grinding, squealing, or pulsing pedal
- Steering: no pull to one side on a straight road, no clunks over bumps
- No vibration at highway speed
- No smoke, burning smell, or new warning light after the drive
Some private sellers won’t allow a test drive. That is a reason to be more careful, or to walk away.
The pre-purchase inspection by a mechanic
Your own checklist catches the obvious problems. A mechanic can put the car on a lift, read stored trouble codes, and check the brakes, suspension, and frame properly.
- Cost: about $100 to $150 for a thorough check, according to Consumer Reports. Confirm the price before the appointment.
- Who: an independent shop you choose, not one the seller picks. The FTC advises an independent inspection even for a dealer-certified car.
- What you get: ask for a written report that lists problems and repair estimates. Consumer Reports and the FTC both say you can use it to negotiate the price.
- If the seller says no: Consumer Reports suggests you may want to walk away.
A vehicle history report doesn’t replace this step. The FTC says such a report typically won’t list mechanical problems.
After you buy
- Write down the date and odometer reading on day one in a car maintenance log.
- Do any overdue basics: oil and filter, and the fluids and filters your owner’s manual lists for this mileage.
- Set the next due dates and miles from the manual, not from the last owner’s stickers.
- Keep the inspection report and the bill of sale with your records.
FAQ
How much does a pre-purchase inspection cost?
About $100 to $150 at an independent shop, according to Consumer Reports. Prices vary by region and vehicle, so confirm before the appointment and ask for a written report.
What should I check when buying a used car?
The VIN, title, and open recalls first. Then the body, tires, under the hood, the interior, and underneath, followed by a test drive. Finish with an inspection by an independent mechanic.
Should I buy a used car with an open recall?
Consumer Reports recommends not buying a car with an open recall until it is fixed. Recall repairs are free at a dealer for that brand. Check the VIN at nhtsa.gov/recalls.
Is a vehicle history report enough?
No. The FTC says it is not a substitute for an independent inspection and typically won’t list mechanical problems. Unreported accidents and repairs won’t appear either.
What does “as is” mean on a used car?
On a dealer’s Buyers Guide, “As Is - No Dealer Warranty” means the dealer won’t pay for problems or repairs after the sale, according to the FTC. State rules on implied warranties vary. This is not legal advice; check with your state attorney general’s consumer office.
